It is not currently possible to set up a single Route with capacity/resource that varies according to resource and item attribute.

e.g. fill rates per bottle size and per machine.

Ideally: create a new attribute on the item (not Item group - often already owned/defined by finance), and allow the same Operation to be specified for each combination of Route, Item route attribute and resource.  The system should be able to determine the optimal Routing line to choose through a bottleneck-type calculation.

Data entry would be possible through a matrix-type form.
